Description

[Detailed Description of the Invention] The present invention relates to the structure of an ultrasonic probe used in an ultrasonic diagnostic apparatus.

Conventionally, ultrasonic probes used in linear scanning type ultrasonic diagnostic equipment have been arranged in a planar manner at an open end provided at the bottom of a plastic case 1 formed in the shape of a rectangular parallelepiped, as shown in Fig. 1. Attach the array transducer 2 and connect the outlet 4 of the cable 3 for transmitting signals between the array transducer and the main body of the device as shown in A, B, and C of Fig. 1. It is installed at right angles or parallel to the direction. However, when the upper part of the probe is held and operated by hand, the cable becomes a hindrance in the case of the top-out type cable installation shown in Figure 1 A and B, while the horizontal-output type cable installation as shown in Figure 1 C Although the grip-type type provides better grip operability, it has the disadvantage that the cable comes into contact with the bed, etc., making it less operable when diagnosing the side of the body of a patient lying supine on the bed.

In view of these points, the present invention aims to reduce the height of the probe by devising the method of attaching the cable outlet, thereby realizing a probe having a structure with excellent operability. FIG. 2 shows an embodiment of the present invention, in which FIG. 2A is a front view and FIG. 2B is a side view. As shown in the figure, in the present invention, the cable outlet 4 is attached to the side surface of the case 1, and the axial direction of the attachment outlet is set at an elevation angle θ with respect to the surface of the array vibrator 2. θ is an acute angle. Furthermore, the mounting position of the outlet 4 is not limited to the side surface, but may be at the corner between the side surface and the top surface.

If the outlet 4 is installed diagonally in this way,
Since less space is required for bending the cable core within the case 1, the height h of the case 1 can be appropriately reduced.

As described above, according to the present invention, since the cable protrudes diagonally upward from the corner of the probe case, the case can be easily grasped and operated without being obstructed by the cable. A sonic probe can be realized.

In addition, by making the cable outlet diagonal as in the present application, the space required for wiring can be made smaller than in the past, making it possible to reduce the height of the probe, which allows for probe operation. It has the effect of further improving sexual performance.
